On March 1, 2013, the great white shark (Carcharodon carcharias) received protection (pdf) under the California Endangered Species Act (CESA).  The protections prohibit anyone from hunting, pursuing, or otherwise harming the species.  Commercial fisheries that could incidentally take a shark in fishing nets, as well as scientists wishing to tag a shark for research, will have to obtain permits from the California Department of Fish and Wildlife.  As reported here, the protections are the result of the California Fish and Game Commission's decision to make the species a candidate for protection under CESA.
